摘　　要：介质的流动改善了液体激光器温度分布的均匀性,起到了自我冷却、减小热效应的作用。应用有限单元法,对单侧泵浦液体激光器工作时涉及的传热和流动过程,进行热—流—固耦合分析,完成对液体介质温度场的数值模拟,并研究了介质流速对温度场的影响。研究结果可为改善液体激光器的冷却效果提供指导。The unifomrity of temperature distribution in liquid laser systems was improved by medium flows, and the negative thermal effects were decreased by this self-cooling of medium. For the coupled effects between flow and transient thermal conduction happened in a liquid laser system pumped unilaterally, the finite element method was used to analyze the thermal-flow-solid interactions, and the numerical results of temperature and its gradient of liquid medium were obtained, moreover the influence of fluid relocity on temperature distribution was also studied. The results presented in this paper provide a guide for improving the cooling effect for liquid laser systems.
